What Hand Soap do you guys use?

I use gas.
If i don't have any gas handy, then i use brake clean or lacquer thinner.
Solvent and diesel fuel are not as good, but will do in a pinch.
Then i go eat a 4 piece KFC chicken dinner and wash my hands in the bathroom after i eat at the restaurant.
Perfectly clean after that, guaranteed.
It's finger lickin' good.
